The purpose of this study was to examine the instructional costs of inclusi
ve and traditional noninclusive special education services for the preschoo
l children with disabilities. Cost information was collected from five loca
l education agencies in different parts of the country that provided inclus
ive and traditional special education service options. Within-agency compar
isons suggested that inclusive models were generally less expensive or comp
arable in cost to traditional forms of special education. Cost features, su
ch as salaries, childcare tuition, equipment, materials, transportation, ad
ministration, and building costs were associated differently with different
models. The difficulty in collecting cost information on noninstructional
costs, the relatively mild degree of disabilities of children in the study,
and potentially different groups of children enrolled in inclusive and tra
ditional models were noted as limitations of this study.
